There is a pressing need to extend our thinking about diplomacy beyond state-centric perspectives, as in the name of sovereignty and national interests, people on move are confronting virtual, symbolic and/or material walls and frames of policies inhibiting their free movement. My point of departure is to explore migrant activism and global politics through the transformation of diplomacy in a globalised world. Developing an interdisciplinary dialogue between new diplomacy and sociology, I evidence the emergence of global sociopolitical formations created through civic bi-nationality organisations. Focusing on the agent in interaction with structures, I present a theoretical framework and strategy for analysing the practices of migrant diplomacies as an expression of contemporary politics. A case study from North America regarding returned families in Mexico City provides evidence of how these alternative diplomacies are operating.
